I was told that in Sarnath the Dharmarajika Stupa marks the site for the Buddha’s first discourse (the Dhammacakkappavattana Sutta), and the Dhamekh Stupa marks the site for the Buddha’s second discourse (the Anattalakkhana Sutta). But I was also told just the opposite story: the Dharmarajika Stupa is the site for the Buddha’s second discourse, and the Dhamekh Stupa for the first discourse. Which information is correct?
